Problem with “Unique Values” symbology for line layer.

[Alex Smith]

Hello all,

 

I’m not new to GIS, but am new to MS.  I’m having trouble with line symbology.  I’m trying to display each shapefile feature with different symbology based on a nominal field – similar to ‘unique values’ in Arc products.  In ArcView, I specified a line thickness of 2 and then manually selected the color of each line.   I then exported the map from ArcView 3.2 using gix-export (thanks gix-export developers!). Then I’m trying to preview the map using the Maplab 2.2 ‘preview map’ button.  When I turn on the line layer, the lines do not display at all.  All other layers (polygon, single symbol) are displaying as expected.  Below is an excerpt from the .sym file.  The name of the line layer is Reaches.  

 

<Begin .sym excerpt>

 

SYMBOL

   NAME 'Reaches--0--0'

   FILLED true

   TYPE ellipse

   POINTS 1 1 END

END #SYMBOL

 

SYMBOL

   NAME 'Reaches--1--0'

   FILLED true

   TYPE ellipse

   POINTS 1 1 END

END #SYMBOL

 

<End .sym excerpt>

 

And below the portion of the .map file that defines the “Reaches” layer symbology.  I removed the metadata portion that gix-export created.

 

<Begin .map excerpt>

 

  LAYER

    NAME "Reaches.shp"

    #    TILEINDEX ''

    #    TILEITEM  ''

    STATUS OFF

    DATA "reaches.shp"

    TYPE LINE

    CLASSITEM "NUMCLASS"

    UNITS DD

    SIZEUNITS MILES

    LABELCACHE ON

    #METADATA

    TOLERANCE 3

    TOLERANCEUNITS PIXELS

    TRANSFORM TRUE

    #Reaches.shp

    TRANSPARENCY 100

    HEADER "header.html"

    FOOTER "footer.html"

    DEBUG true

    CLASS

      NAME "1"

      EXPRESSION "1"

      TEMPLATE "template.html"

      #PEN

      STYLE

        SYMBOL "Reaches--0--0"

        COLOR 37 59 55

        SIZE 1

        MINSIZE 1

        MAXSIZE 100

      END

    #STYLE

    END

    #CLASS

    CLASS

      NAME "2"

      EXPRESSION "2"

      TEMPLATE "template.html"

      #PEN

      STYLE

        SYMBOL "Reaches--1--0"

        COLOR 255 215 0

        SIZE 1

        MINSIZE 1

        MAXSIZE 100

      END

    #STYLE

    END

    #CLASS

 

<End .map excerpt>

 

I tried comparing all of the layer, class and style parameters/args with those of the “roads” layer in the MapLab tutorial.map file.  I can’t find anything that is different, with the exception of the use of the symbol file.

 

Any help that you can provide to this noob would be appreciated!
